5 Claims. l.

The present invention relates in general to improvements in lock hasps and more icularly is directed to lock h fps of the type ha .lng a pro jecting notched keeper tongue, sped' cally for use upon hrief cases, trunks, travelling bags and the like.

-leretofore it has heen coninlon practice in making lock hasps of the type having a notched keeper tongue projecting perpendicularly the hasp body and in planes parallel or trans verse to the longitudinal medial l of the hasp from a point spaced upwardly from the lower end thereof, to form the hasp hotly in the de sired shape by stamping blanks or sheet material into the desired coniiguration for the cody and securing thereto a separate projecting tongue by brazingV Welding or like operations. These sepam rate operations required to individually form the hasp body and tongue element into desired and securely attach the tongue to the hasp body in a manner that it will resist the severe stresses to which the keeper tongue is normally subjected, are relatively time-consuming and ei;- pensive.

Also, as is disclosed in the earlier Patent No. 1,95l,'55l, issued March 20, 193.41, to A. T. Long, a lock hasp having a rearwardly pro eye catch or staple been ier'VV 'd fro/.n blank or" `metal. In this coi t lotion, the blank is provided with lateral eite projecting from the hasp hotly which provided with slots adapted to receive a keeper holt. le projections are bent in overlyii'g rela-non W l the rear face of the hasp hodv, the entrern ties of the extensions having the slots therein leent rearivardlv at right angles to plane the hasp so that the slots are brought in e ment with each other to provide the staple. a construction, however, attended inai disadvantages, such as the diiiculty of constructing dies which will provide accurate ina-t the two separate lateral extensie 1s and will hij the extensions into perfect intent to tornthe complete staple extending in a intersecting the medial axis ot the hasp body.

An obiect ot the present invention, therefore. is to olivia-te the diinculties incident to semrate production of the lock hasn and t in the production ot' a nnished lock of this general character by forming the look harp notched keeper tongue from a of metal.

strength anolresistance to deformation by thel stresses incident to use of such lock hasps.

Another object of the present invention isthe provision of an improved one-piece construction for a lock hasp of the type having a notched keeper tongue projecting from the inner surface thereof ina transverse plane perpendicular to the longitudinal medial 'axis of the hasp body, which is formed from a single blank of metal with the parts bent in required pos. ion and in terrelate'd in such a manner that each contributes to the strength and resistance to stress of the other parts. A

Another object of the pres t invention is the provision of a novel lock ha of the character having a notched keeper ton ue proie'cting from the inner surface oi the lia-sp body along a transverse pla-ne perpendicular to the medial thereof by forming the lock from a single piece oi" metal which the parts are so arranged by suitable bending and shaping thereof to mutually contribute to the strength of each of the parts and to leave no exposed unattractive surfaces or edges.

Another object of the present invention is the provision oi' a novel lock hasp of type having a rearwardly projecting notched keeper tongue, which is formed from a single blank of metal with the parts so arranged by suitable bending and shaping thereof to produce a hasp of more attractive and advantageous arra, .ement oi parts, preserving an apparent uniformity of thickness of the hasp body, eliminating exposed fold ends and edges, and providing a smooth re. r contact surface devoid of abrupt variations in thickness to permit accurate of the hasp body With the lock plate.

Other objects, advantages and capa-oilities of the present invention will become apparent from the following detailed description n conn junction with the accompan., dra ings, wherein only a preferred embodiment of the invention is shown.

In the drawings:

Figure 1 is a front elevation of a look hasp of the type having an integral keeper tongue projecting from the inner surface of the hasp body in a transverse plane perpendicular to the medial axis of the body, constructed in accordance with the present invention;

Figure 2 is a plan View of the blank of sheet metal material from which the lock hasp is formed;

Figure 3 is a rear elevation of the lock hasp body showing only the lower portion thereof, illustrating the specific arrangement of the projecting notched keeper tongue on the hasp body in the finished product;

Figure 4 is a vertical section of the lower portion of the lock hasp body taken along the lines 4 4 of Figure 3;

Figure 5 is a transverse section illustrating the interrelation of the proecting keeper tongue with the bent anges of the lock hasp body, taken along the lines 5-5 of Figure 3; and

Figure 6 is a horizontal transverse section of the lower portion of a modified form of lock hasp body, showing struck over flange portion for retaining the tongue plate in position.

Referring particularly to the drawings, wherein like reference characters designate corresponding parts throughout the several figures, the hasp body, generally indicated by the refer ence character Iii, is adapted to be hingedly or pivotally coupled to a hasp plate I2 by means of a hidden pintle or pivot pin i4 which extends through a sleeve head I6 formed from the hasp body l by rolling a portion of the upper end of the hasp body into tubular form.

The hasp plate I2 is of the conventional type provided with apertures for mounting the hasp plate on a suitable trunk, traveling bag or the like, by means of screws. The sleeve head I6 is located between corresponding rolled ear sockets or sleeve formations I8 which are formed integral with the hasp plate I2 and into which the ends of the pivot pin I4 extend to provide the pivotal coupling between the hasp body IS and the hasp plate I2.

The opposite longitudinal edges of the hasp body IE) are each bordered by a rearwardly projecting flange 20 which is integrally formed with the hasp body I0. Tightly secured between the flanges 20, at the lower end of the hasp body, is the tongue plate 22 which, as illustrated in Figure 2, is formed integral with the hasp body I0. The notched keeper tongue 24 is formed integrally with the tongue plate 22, and extends from the end thereof at right angles to the inner surface of the hasp body I!! in a plane perpen dicular to the longitudinal medial axis of the hasp body. The tongue is provided with notches 25 in the opposite side edges thereof adjacent the throat of the tongue for engagement by keeper portions of a suitable lock (not shown) with which the hasp may be used.

The single blank of sheet metal from which the lock hasp is formed is illustrated particularly in Figure 2, the illustration in Figure 2 being provided with dotted lines 26, 25', 2l and 28 illustrating, respectively, the bend or lold lines along which the tongue plate 22 is bent back into overlying relation with the rear surface of thel hasp body IB, the longitudinal edge anges 2S are bent into rearwardly projecting substantially perpendicular relation with the rear surface of the hasp body, and the tongue 24 is bent into right angular relation with the tongue plate 22 4 projecting rearwardly from the overlying tongue plate 22 and hasp body I0.

Projecting ears 28 are formed at the throat or base of the tongue plate 22 adjacent the hasp body It to cover the lower edges or ends of their adjacent flanges 20, the ears 29, for this purpose, being cut back at their upper edges adjacent flanges 2 to a point in line with the bend or fold lines 2'I.

The lock hasp is formed by bending notched tongue portion 24 forward toward the front of the lock hasp along the bend line 26 into a position lying at right angles to the tongue plate 22. The tongue plate 22 is then folded rearwardly through an arc of one hundred eighty degrees along fold lines 25 and 26 into a position overlying and in intimate contact with the rear surface of the hasp body I0, as illustrated in Figure 4. The longitudinal edge flanges 20 are then bent rearwardly along fold lines 2 through an arc of approximately ninety degrees into a position extending perpendicular to the rear face of the lock hasp IS and intimately engaging the sides of the tongue plate 22. Suitable adhesives may be disposed between the overlying faces of the tongue plate 22 and the hasp body IB, and the side edges of the tongue plate 22 and adjacent portions of the flanges 2l. In this position the laterally projecting ears 29 at the throat 0r base of the tongue plate 22 will be extending laterally in intimate overlying relation with the otherwise exposed lower edges of the flanges 20, The outer ends of the laterally extending ears 29 disposed in covering relation with the lower ends of the flanges 2i) may then be finished off or burnished to form a round corner 22a.

In the modiiied form illustrated in Figure 6, the inner edges of the iianges 2) along the lower portion thereof are struck over the adjacent portions of the tongue plate 22 forming projections S overlying the lateral edge portions of the tongue plate 22 to aid in maintaining the tongue plate in overlying relation with the hasp body in opposition to deforming stresses imposed on the tongue plate in use.

It will be readily seen that the lock hasp may be conveniently stamped out of a single piece of metal in an approximate manner to form an integral lock hasp of the type having a rearwardly projecting notched keeper tongue extending in a plane perpendicular to the longitudinal medial axis of the hasp body, and in which the disposition of the right angular iianges 2] intimately abutting the sides of the tongue plate 22 assist in maintaining the keeper tongue in proper position and facilitate the resistance to the stresses imposed during use of the lock hasp. As a result, this lock hasp may be more economically produced than can be done where the parts are separately formed and secured by welding, riveting or the like.

While but one specic embodiment of the invention has been particularly shown and described, it is distinctly understood that the invention is not limited thereto, but that various modifications may be made without departing from the spirit and scope thereof, and it is desired, therefore. that only such limitations shall be placed thereon as are imposed by the prior art and are set forth in the appended claims.
